This time our branch [lp:~cern-kicad/kicad/drawing_tool] brings some
drawing tools to the GAL canvas in pcbnew. The most important changes:
- tools are bound to the respective buttons on the right toolbar (there
is no "Selection tool" or "Interactive router" entry in menu)
- new tools make possible to draw zones, lines, circles, arcs (the last
one is a improved a bit; '/' changes the direction of arc) and place
modules, texts, dimensions and targets

- you can change the line width while drawing (using -/+ keys)

- by default you can draw lines/zones at any angle; to enable 45 degree
mode (resembling push and shove router) you may hold Ctrl while drawing
- after selecting a single graphical item, you will see edit points that
allow you to modify vertices by dragging them; it also supports 45
degree mode activated by holding Ctrl

You may have a look on a short demo presenting the mentioned features:

it yourself).
